- * finalize the API:
- - which PCM output format (s24,s32,float...) ?
- - any special needs for the extensions ?
- * implement missing features:
- - check output gain! I couldn't find anything in the spec about this so
- right now I'm assuming the output of the 32 subbands QMF is supposed to
- be in 16 bits/sample form but this seems very dubious.
- - fix downmix (user proper channes coefs, move downmix before QMF)
- - sum/difference audio channels
- - joint channels coding
- - dynamic range
- - dialog normalization
- - check audio output accuracy (right now the main issue is the output gain)
- - extensions (96k, extra channels)
- * optimize:
- - don't use doubles everywhere
- - integerize everything ? (main difficulty should be the QMF and LFE FIR)
- - faster 32 subbands QMF
- * reliability:
- - make the parser more tolerant to faulty bitstreams
- - more sanity checks
- - crc checks
- - regressions tests
- * code cleanup
